If investors are ordinary etf funds, they will not be forced to close their positions. If they buy etf funds through financing, they may be forced to close their positions. When investors have incurred relatively large losses, they will be forced to sell by securities companies. If investors add additional funds, they will not be forced to close their positions. Only when the general subject matter reaches the compulsory liquidation line will the securities company be forced to liquidate.

Ordinary trading etf funds are investors' own funds and will not be forced to close their positions. However, in the process of investment, they have already incurred relatively large losses, and investors can take the initiative to sell. When financing to buy etf funds, the securities company will only lend the funds or securities to investors after the investors transfer the collateral into the brokerage account. Suppose the investor's collateral suddenly plummets and the collateral funds are insufficient, and the investor needs to transfer the collateral again. Otherwise, the securities company will force investors to close their positions.
